Native basis

A <header>: the title with the comment count (a Badge), the sort - a native Select inside its <label>, or sort links with aria-current - and optional actions.

Built from

Badge, Select, Button, Toggle Group, Avatar, Alert.

Web Platform APIs

<select><label>aria-current

Classes

.mk-comment-header.mk-comment-header-title.mk-comment-header-actions.mk-comment-header-sort.mk-comment-header-tabs.mk-comment-header-people

Data attributes

data-variant="plain"; .mk-comment-header-tabs for sort links; .mk-comment-header-people (an Avatar group + a sentence).

§Default

Title with the count (a Badge), the sort - a native Select in its label - and a follow action, over a rule.

§Sort links

The sort as links (aria-current marks the order) in a segmented row - no script at all; data-variant='plain' drops the rule.

§Toggle sort and participants

The sort as a Toggle Group (single), and who is talking - an Avatar group with a sentence on its own row (.mk-comment-header-people).

§Closed

A closed thread: the header stays, an Alert explains - the count still tells how much was said.
